“…Auditory noise has the potential for fall prevention for people with instability due to visual, vestibular, or somatosensory deficits. Peripheral sensory deficits can lead to more reliance on audition for balance (Dozza et al 2007;Hegeman et al 2005;Palm et al 2009), and auditory noise can reduce postural fluctuations, so auditory noise should be tested for its ability to improve balance in these populations.…”

“…Auditory stimuli with changing acoustic properties, as in Hegeman et al (2005) and Dozza et al (2007), could result in mixed and inconsistent effects on sway if the acoustic properties themselves influence sway. Palm et al (2009) found no effect on sway with music from a fixed location. Deviterne et al (2005) found reduced sway when participants listened to speech, but not when they listened to a single sustained tone.…”

“…Impairment of vision, proprioception, or vestibular systems leads to more reliance on audition (Dozza et al 2007;Hegeman et al 2005;Palm et al 2009), and hearing loss has been shown to increase variability in postural sway, although the explanation for this is unclear. Juntunen et al (1987) proposed that subclinical damage to the vestibular system with noise-induced hearing loss could explain the effect on stability, but there is no corroboration for vestibular damage in their participants because of the difficulty in examining damage too subtle for current clinical detection.…”

Abstract. According to Latvia's statistical data, for the first time during the period from 2005 up to 2011, more than 3115 people were registered with the eye and it's parts diseases. The aim of the study was to assess postural parameter for people with severe visual impairment. The study involved visually impaired Social Care Center "JUGLA" occupiers, with the 1 st and the 2 nd visual impairments disability group. Participants were interviewed, posture was assessed (Kendall) and anthropometric measurements were taken. The majority -53.6% the study participants were 1 st group visual handicaps (mean age 47.9 ± 10.6 years). 82.1% the study participants had a straight backbone in the frontal plane. The cervical spine of 10.7% the participants had a normal position in the sagittal plane, for 32.1% the participants normal position was observed in the thoracic spine and for 39.3% -in lumbar spine. Faulty postural alignment in frontal and sagittal plane was equally often observed for the 1 st as well as for the 2 nd group visual handicaps. The most common postural type in the sagittal plane for the participants was kyphotic -lordotic posture.

“…8,9 Thus, afferent information from the vestibular, visual, proprioceptive and interoceptive systems are essential for integrating the body with space and to maintain postural balance. [10][11][12][13][14][15] At present, there are several tools for quantifying body balance, such as force platforms, baropodometry, and 3D electromagnetic sensors. Using these tools, however, may be expensive and time-consuming, and requires expert labor to acquire and analyze data; thus, these tools are not used as often as wished in clinical and some research settings.…”

Earl y detection of postural disorders is essential for timely interventions in patients with imbalance. Aim:A pilot study describing a new tool for evaluating static postural balance.Study Design: A cross-sectional study of a contemporary series. Material and Method:Twenty-five volunteers (15 women and 10 men) were evaluated. The mean age was 25.8 ± 4.2 years, the mean weight was 63.9 ± 13.1Kg, the mean height was 1.68 ± 0.08 m and the body mass index was 22.3±3.3kg/m2. Posturography was done by analysing postural sway with an electromagnetic system; a sensor was attached to the skin over the spinous process of the first thoracic vertebra. Tests were carried out with the subjects in the orthostatic position for 90 seconds, with eyes opened(EO) and closed(EC) on stable and unstable surfaces.Results: When the influence of the surface was analyzed (stable x unstable) in the EO condition, there were significant differences in the middle-lateral parameters (m-l) (p=0.004) and total path (p=0.01), and in the m-l (p=0.004) and total (p=0.014) speed. In the EC condition, there were significant differences in all parameters (p<0.001). The influence of the vision was observed in all parameters only on unstable surfaces (p<0.05). Conclusion:The new tool was efficient for analysing postural sway. Braz J Otorhinolaryngol. 2010;76(6):783-8. ORIGINAL ARTICLE BJORL
